The libbacktrace/Makefile.am uses a shortcut:
...

std::vector, which means that the type depends on whether debug mode is

* c-decl.c (last_fileptr_type): Remove.

last_structptr_types array has the same number of elements

argument oldtype and newtype. Instead of handling
just fileptr_type_node specially, handle all builtin_structptr_types
pointer nodes. Formatting fix.
